Question

Helicopters can land on circular pads. The area of a landing pad is 1,962.5 square feet. What is the radius of the pad? Use 3.14 to approximate pi.

Answer 1

The answer would be 25 feet

Explanation:

1,962.5 ft2 = 3.14 • 25 ft2

Answer 2

25 ft

Explanation:

The area of this landing pad is 1,962.5 ft², which equals πr².

We solve this equation for r²:

1962.5 ft²

r² = ----------------- = 625 ft²

3.14

Taking the square root of both sides, we get:

r = √(625 ft²) = 25 ft

The radius is 25 ft.
